Nope. It's in reverse.
In DEV they were updating a non PI column which was placing ROW HASH locks (so updates succeeded) and in PROD the updates were on PI column
Placing table level lock, leading to Deadlock (due to the application design/huge parallel sessions, some sessions holding locks already and
others requesting/waiting for access).
